[0015] In an optional solution, the inner wall of the joint is in sliding contact with both the outer walls of the docking flange B and the docking flange A.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In the utility model, the pipe body, the expansion joint and the joint cooperate to form a sewage pipe. After the docking flange A and the docking flange B are docked, the joint is placed on the outside of the docking flange A and the docking flange B to form a protection and rotate. The docking flange A and the docking flange B are connected by the cooperation of the joint and the arc plate. After that, the joint can be connected to the docking flange A, which can ensure the stability of the pipe connection and enable the pipe to be stably connected and laid.

[0018] In the utility model, the pipeline will expand and contract due to changes in ambient temperature during use, resulting in changes in the length of the pipeline. The expansion joint can absorb the axial, lateral and angular expansion and contraction caused by the temperature change, thereby increasing the service life of the pipeline. During the installation of the pipeline, due to site conditions or design requirements, it is sometimes necessary to adjust the length of the pipeline. The expansion joint can serve as a length compensator to meet this adjustment requirement. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The docking flange A14 and the docking flange B15 are both provided with three sets of arc grooves 16. A curved plate 26 passing through the arc grooves 16 is connected to one side of the joint 12. A curved sealing block 23 engaging with the arc grooves 16 is slidably connected to the annular inner wall of the joint 12.

[0028] The annular side wall of the joint 12 is provided with a limiting hole 21, and the annular side wall of the docking flange A14 is provided with a limiting screw hole 20 corresponding to the limiting hole 21;

[0029] In this embodiment, after the docking flange A14 and the docking flange B15 are docked, the arc plate 26 and the arc sealing block 23 pass through the arc groove 16, and then the joint 12 is rotated. The arc sealing block 23 can be placed in the arc groove 16, and the arc plate 26 and the arc sealing block 23 are staggered. At this time, the movement of the docking flange A14 and the docking flange B15 can be restricted, so that the docking flange A14 and the docking flange B15 are stably attached. At the same time, the arc sealing block 23 is placed in the arc groove 16 to play a sealing role, reducing the accumulation of impurities in the arc groove 16. Bolts corresponding to the limiting screw holes 20 can be used to connect the joint 12 and the docking flange A14, so that the pipeline body 11 and the expansion joint 13 are stably connected, or adjacent pipeline bodies 11 are stably connected.

[0030] The end of the pipe body 11 away from the docking flange B15 is connected to the docking flange A14, and the end of the expansion joint 13 away from the docking flange A14 is connected to the docking flange B15; adjacent pipe bodies 11 can be connected through the docking flanges A14 and docking flanges B15 on their respective pipe bodies 11.
